Al-Zahrawi (936 – 1013) used the same procedure for removing cataracts that earlier Muslim doctors had copied from the Hindus and Byzantines.
He made some improvements to the Hindu and Byzantine plastic surgery on eyebrows and eyelids. Al-Zahrawi designed an instrument to hold up the upper eyelid while examining the eye.
The late 10th century Muslim eye physician Jesus the Oculist was the first to discover the symptoms of Vogt-Koyanagi-Harada syndrome, and the first to describe temporal arteritis.

European medieval cataract surgery was probably borrowed from Muslims who had borrowed from the Byzantines and Greeks.
Al-Zahrawi (936 – 1013) used a surgical procedure for removing cataracts. I assume it was the suction needle used to remove soft cataracts, a procedure that had been used in the 2nd century by the Greek physician Antyllus. Muslims learned about it by making shopping trips to the Byzantine Empire to purchase medical books.
Al-Zahrawi was not the first to perform eyebrow and eyelid plastic surgery http://www.ncbi.nlm.nih.gov/pubmed/9734459/
but Al-Zahrawi may have described it in more detail than the 4th century Byzantine medical books had.
One of Al-Zahrawi’s lower eyelid surgery procedures is now called the Kuhnt–Szymanowski procedure.
The Roman surgeon Celsus had centuries earlier written about eyelid surgery.
Several Muslim physicians knew about Hindu medicine of India by having read an Arabic translation of the Sushruta Samhita.
The Uttara-Tantram (a supplement to the Sushruta Samhita) had chapters 2 and 3 devoted to eyelids. http://books.google.com/books?id=5cE0AQAAMAAJ&pg=PA26&lpg=PA26&dq=sushruta+samhita+eyelids&source=bl&ots=rcEvg0hNHt&sig=kRCUCkx5ls_Gc7P87_j08HEyD8I&hl=en&sa=X&ei=sW4aVIHzM9i9ggTH-4DQAQ&ved=0CBwQ6AEwADgK

JESUS THE OCULIST
Late 10th century Baghdad eye physician Ali ibn Isa al-Kahhal (Jesus the oculist) illustrated the optic chiasm and brain, was the first to discover the symptoms of Vogt-Koyanagi-Harada syndrome, and the first to describe temporal arteritis. [In Islam, Jesus is only a minor prophet.]
